The Pit is widely regarded as the worst of the Virgin New Adventures novels. I only have dim memories of the one time I read and I recall mostly being a bit bemused and feeling that William Blake was underused. I recently listened to the Doctor Who Bookclub podcast discuss the book and they certainly didn't like it much. Their final conclusion was that there were some potentially interesting ideas in there, but that the execution failed to explore them in a way that brought anything much to life, and the structure meant the whole story ultimately felt rather pointless with the Doctor, Benny and Blake making no real impact on the events.

All I can recall of it is such epic boredom I'm not in the least bit tempted to revisit it! It did at least have an appropriate name. I suppose they couldn't get away with calling it "The Worst NA" but they did their best!

I seem to remember that Benny provided the only fleeting moments of non-boredom, but I couldn't swear to it.
